The words "homophobia", "transphobia", "xenophobia" and "islamophobia" all mean phobia, not hatred, of certain groups (hence the uses of the word "phobia" in them). They are all cretinous newspeak words. And if the word "christophobia" existed (Which it does not because a red squiggly line appears under it, unlike the word "islamophobia". See the unfairness here?) then I would agree that it is a cretinous newspeak word as well.
